undefined reference to `flash_binary' (ESP Serial Flasher using ESP-IDF)

I build the code above using ESP-IDF, the IDE is VS code platformIO.
I faced a problem after building the code above based on the default ESP Serial Flasher from Espressif.
The error resulted from the build is as follow:
c:/users/user/.platformio/packages/toolchain-xtensa-esp32s3/bin/../lib/gcc/xtensa-esp32s3-elf/12.2.0/../../../../xtensa-esp32s3-elf/bin/ld.exe: .pio/build/esp32-s3-devkitc-1-n16r8v/src/main.o:(.literal.app_main+0x20): undefined reference to `flash_binary'

Any solutions for this? Thanks in advanced.
